Challenge Problems
Push your limits with challenges.
Question 1
An RL series circuit with R = 50Ω and XL = 70Ω is connected to a 240V supply. Calculate the total impedance, current, and verification with voltage drops.
💡 Hint: Break down calculations for impedance, then apply Ohm's law systematically.
Question 2
Design a similar RL circuit to operate at a specific current of 5A at a voltage of 120V. Calculate R and XL, ensuring the phase angle meets standard applications.
💡 Hint: Explore R and XL dimensions to fit within limits defined by system constraints.
